Q:Common faults of DC invert manual arc welding machine
TroubleshootingThe switch power supply indicator is not on, the fan does not turn, no welding output, 1, confirm the power switch closed.2. Make sure that the input cable is connected to the power supply.Power indicator light, fan does not turn, no welding output 1, may be wrong input on the 380V power supply, causing over-voltage protection circuit start, change to 220VPower on, you can reboot.2, 220V instability (power input line or too long) or input lines overlap in the grid, resulting in over-voltage protection circuit starting, increase input line grid line diameter; the fastening input line node, this phenomenon is shut down 5-10 minutes after the restart recovery.3, a short time continuous open and close power switch, cause over-voltage protection circuit start, shutdown 5-10 minutes later, restart, you can return to normal.4. The wire between the power switch and the power board is loosened and re tightened.5 、 the 24V relay on the power board is not attracted or damaged, check the 24V power supply and relay, and the relay can be replaced by other relays of the same type.When the fan is turned and welded, the output current is unstable or not controlled by potentiometer. When the current is large, it is small 1, potentiometer 1K, and the quality is not good. Should be replaced.
Q:Thin stainless steel by argon arc welding? [around 0.7]? How to use argon arc welding machine? What is the current size of argon?
04 of the thickness of 1.6 wire is too thick, the current is small, welding wire does not burn, the current is large, welding wire is turned, but the pipe can not stand.Argon arc welding is a kind of welding technology using argon gas as protective gas. Also called argon gas shielded welding. That is, argon shielded gas is applied around the arc welding, and the air is separated from the welding zone to prevent the oxidation of the welding zone.Argon arc welding technology is based on the principle of arc welding on using argon protection for metal welding, the welding material in high current to be welded on the substrate is melted into liquid form of molten pool, the metal to be welded and welding welding technology to achieve a metallurgical combination, due to the high temperature melting on argon welding continuous feeding in the welding material can not contact with oxygen in the air, thereby preventing the material oxidation, therefore can welding stainless steel, iron metal hardware.
Q:What is the function of an argon arc welding machine with current attenuation function?
1. Argon arc welding machine with current attenuation function can help arc striking.2, welding, welding materials (welding rod, welding wire, etc.) arc ignition process called arc. The arc striking methods commonly used in manual arc welding are stroke cleaning and direct striking.3, argon arc welding, that is, tungsten inert gas arc welding, refers to the use of industrial tungsten or activated tungsten as non melting electrode, inert gas (argon) as the protection of welding methods, referred to as TIG.
Q:Circuit diagram of WS-160 DC argon arc welding machine
What's wrong with your welding machine?The remedy to the disease is better
Q:What are the main types of AC hand arc welding machines used for welding?
When used as the cathode of aluminum, crushing effect. Usually welded carbon steel, stainless steel are used DC, but the welding machine on the market is either DC or AC and DC dual-use, and if you want to use welding aluminum, it is best to buy AC and DC dual-use.
Q:What are the characteristics of rotary DC arc welding machine?
The machine is composed of engine (diesel or gasoline generator (drive), single-phase or three-phase AC arc welder,) and composition, is a set of power generation, power supply and power as an independent power system, can be used as a generator, and can be used as a welding machine, which is called generating welding machine.
Q:Argon arc welding without arc welding -- Shanghai universal argon arc welding machine WSE-315-1
If it is not out of line transformer are bad phenomenon, usually due to electric shock in the short distance from the picture above transformer, high frequency discharge energy shortage, suggestions will shock large distance try.
Q:WSM-200A inverter DC pulse argon arc welding machine access voltage, what parts of the assembly damage?
Wsm-200's machine is 220V, and if you receive 380V, usually burn the insurance first, and if you don't burn the filter, the filter capacitor is the first one to go wrong, and the most wrong power I've got is the capacitor.
Q:What do you mean by "ground arc" of argon arc welding machine? Is it because it doesn't arc or is it connected directly to the ground to prevent electric shock?
Some of the ground wires come from the positive electrode, some from the negative electrode, and the electrodes are marked or referenced. The electrodes are directly connected to the welded metal objects before welding.
Q:Can argon arc welding machine weld copper?
Can. But the cost is high. It is difficult to weld brass (including zinc) by argon arc welding.
